TRACK S CRAPER Filed Nov. 29, 1937 Patented Dec. 19, 1939 UNITED STATESPATENT OFFICE 5 Claims.

This invention relates to a scraper and, more particularly, to a trackscraper for use in cleaning the roadbed of a railroad.

It is desirable to frequently clean the coal, refuse, etc., from betweenand around the rails of a railroad, especially in coal mines, as therails and roadbed become littered with coal which falls from overloadedcars and from the mine roof. Such an accumulation of coal and refusealong the track not only tends to block the passageway but constitutes ahazard to the workmen and has to be periodically removed. It is theusual practice to remove this material entirely by hand, which is alaborious and an expensive operation since the material is very muchscattered and lies between the rails as well as on the sides thereof.

It is an object of this invention to provide a scraper which willreadily and inexpensively remove tlie coal and loose material frombetween and around the rails.

It is another object of this invention to provide a scraper which willremove loose material from the roadbed between the rails as well as thatalong the outside of the rails and concentrate the same in one placewhere it can be conveniently removed later.

It is a further object of the invention to provide a track scraper whichis simple and inexpensive in its construction and which can be easilyand quickly adjusted relative to the roadbed.

Various other objects and advantages of my invention will more fullyappear during the course of the following specification, and will beparticularly pointed out in the appended claims.

In the accompanying drawing I have shown, for the purpose ofillustration, one embodiment which my invention may assume in practice.

In the drawing:

Figure l is a plan view of the improved track scraper of my invention;

Figure 2 is a side elevational View of the same, and

Figure 3 is a detail plan view of the angularly disposed side scraper.

According to the invention, there is provided a truck comprising a bodyportion 2 having sidewalls 3, end-walls l and wheels 5 which are adaptedto run along suitable rails on the roadbed. There is carried by the body2 between the side-walls 3, preferably in the central portion thereofbetween the front and rear wheels, an angularly disposed scraper 6having, preferably, a turned-out lower edge. This scraper is mounted inopposed. staggered guideways l' which are carried by the inner surfacesof the side-walls 3 of the body 2. The scraper is suspended in theguideways by means of a yoke portion 8 which is attached to the end of athreaded screw 9 by means of a chain I0. 5 The screw 9 is looselymounted for vertical movenient in a journal II which is, in turn,mounted on a cross-beam or member I2 which extends from one side-wall tothe other across the top of the truck body. There is provided on the end10 of the threaded screw 9 a hand-wheel I3 which is adapted to rest onthe journal II to support the scraper B. The scraper 6 is adjustedvertically relative to the roadbed between the rails by means of thishand-wheel. The scraper also 15 has a horizontal side-extending portionI4 which is adapted to extend over one of the rails to deflect the loosematerial from between the rails thereover.

There is positioned rearwardly of the end of 20 the extending portion I4of the scraper 6, to one side of the body 2 outside the rails, a secondangularly disposed scraper I5 also preferably having a turned-out loweredge and having one end attached to the lower end of a spindle I6 which25 is rotatably mounted for vertical movement in bearings I1 on theouter surface of the truck body. This spindle has an upper threadedportion I8 which extends above the upper bearing I'I and has mountedthereon a hand-wheel I9 for 30 vertically adjusting the scraper I5relative to the roadbed outside of the rails.

The scraper I5 is adapted to be adjusted angularly relative to the railsby means of a link member 20' having one end connected to the 35 scraperrearwardly of the spindle connection (to the scraper) and its oppositeend connected to a crank-arm 2l which is, in turn, connected to the endof a spindle 22. The spindle 22 is loosely mounted in bearings 23 whichare mounted on 40 the inner surface of the side wall 3 of the bodyrearwardly of the spindle I6. A hand-wheel 24 is mounted on and keyed tothe upper end of the spindle 22 above the upper bearing 23 for turningthe spindle I6 to angularly adjust the scraper.

It will be seen that, in operation, the scraper 6 is adjusted verticallyrelative to the roadbed between the rails and the scraper I5 adjustedboth vertically relative to the roadbed outside of the rails andangularly relative to the rails 50 and the clearance along the side ofthe rails, and the scraper truck moved along the tracks by any suitablesource of power. The loose material is scraped from between the tracksby the scraper S and deflected, due to its angular position, to 55 oneside and over the rail into the path of the scraper l5 which deflectsand concentrates the material to one side of the roadbed or passagewayfrom whence it can be easily and conveniently loaded and removed.

While I have shown and described an embodiment of my invention, it willbe understood that this embodiment is merely for the purpose ofillustration and description and that various other forms may be devisedwithin the scope of my invention, as defined in the appended claims.

I claim:

l. A scraper `for use in cleaning the roadbed of a railroad comprising abody member, a scraping member carried by said body member and beingfloatingly disposed between the rails at an angle thereto, verticallyadjustable means for loosely suspending said scraping member between theside walls of said body, a guideway carried by the opposed side walls ofsaid body with the free endsof said scraping member being loosely andslidably positioned therein, a second scraping member independentlycarried by said body member and dispcsed to one side of said rails at anangle thereto, vertically adjustable means for pivotally attaching oneend of said second mentioned scraping member to the side wall of saidbody adjacent the rearwardly disposed end of the rst mentioned scrapingmember, and means for adjusting said second mentioned scraping memberangularly relative to the rails, said scraping members being soconstructed and arranged that the rearwardly disposed end of the irstmentioned scraping member is positioned just ahead of the forwardlydisposed end of the second scraping member so that the materialcollected from between the rails by th-e iirst mentioned scraping memberwill be defiected over one of the rails into the path of said secondmentioned scraping member which, in turn, deflects the material to oneside or" the roadbed.

2. A scraper as defined in claim l wherein the vertically adjustablemeans for pivotally attaching the end of the second mentioned scrapingmember to the body comprises a vertically disposed spindle pivotallypositioned in bearing members carried by the body, the bottom end ofsaid spindle being securely attached to the second mentioned scrapingmember adjacent the end thereof and the upper end having a threadedportion with a hand-wheel disposed thereon directly above the uppermostbearing member for adjusting the vertical position of said scrapingmember.

A scraper as defined in claim 1 wherein the adjustable means forloosely suspending the scraping member comprises a chain having itslower end connected to the scraping member with its upper end connectedto the lower end of a spindle which is loosely positioned in a journalmember carried by the body member, the spindle having an upper threadedportion with a handwheel disposed thereon directly above the journal forvertically adjusting the position of -iioating scraping member betweenthe rails.

4. A scraper as defined in claim 1 wherein the means for adjusting saidsecond mentioned scraping member angularly relative to the railscomprises a vertically disposed spindle pivotally positioned in bearingmembers carried by the body, the lower end of said spindle having acrankarm securely arranged thereon with the outer end of said crank-armpivotally connected to one end of a link, the opposite end of the linkbeing pivotally connected to the second mentioned scraping memberintermediate the length thereof and a hand-wheel securely arranged onthe upper end of said spindle directly above the uppermost bearing foradjusting the angular position of said scraping member relative to therails.
